Surrounding the forward end portion of: the body B. isa reinforcing hood H in close contact at substantially all points with the. bottom wall I andside walls 2 of the body Band with the upper I edges. of the side members 6 of the hood sub stantially flush with the upper edges of. the: side walls 2.. a

The hood H has its forward edges substantial? lyfiush. with the forward edges of the. side-walls [and said. side members: 6 extend a material distance-inwardly of the bucket. B with the inner or rear edges of said side members 6 extending downwardly-and outwardly on a. predetermined. curvature. This hood H is welded to the body B. The lower forwardv portions of the side meme-- here 6 of the-hood H are cut away, as at'l, in a: manner substantially conforming to the cut-away portionsrof the side wall 2 and the forwardedge of the. bottom part. 8 of the hood. H isformed with. a downward and forward bevel 9 with said beveled portion 9 extending beyond the bottom wall I of the body B, whereby said beveled porttion 9, provides-a digging blade, theefli'ciency' of.

which is facilitated by the cut-away portionsri and l...

Bridging the forwardxend of the body-B and disposed thereabove is a curved plate In, of'idele sired ra'dius and which has its end edges resting upon theiforwardsportions of the upper edgesot the side-.members-G of the. head H and welded theretoi' The forward edge of the plate H1 is flush with the forward edgesof the side member 6 of the; hood Resting upon theztopof the plate mis'areim forcing member H of channel form and which member: isv of such size asto have its extremities overl-ierthe-rupper portions of the hood H; The sidefianges a of: this rein-forcing member l l 'have direct contactfwith. the plate id and" are secured thereto by welding. The lower portions of these flanges.- a: also direct contactwith the'si'd'e member 6 of the hood H and secured thereto by welding; and theilower or free ends of thepart of the channel. member H lying between the flanges a arecurved inwardly, as: at $2 to close said end portions of the member II. This member H is also of a width closely approximating the width of the curved plate to.

At the central or high portion thereof the member H has disposed transversely thereacross a hood socket connection S. As herein embodied, this connection S comprises a pair of spaced but closely adjacent upstanding lugs l4 having their upper margins inclined downwardly and forward- 1y, as at b, with the rear high portions of the lugs 14 provided with the openings l5 and 16 through which is directed the holding pin I 1 for the dump rope socket P, herein illustrated as a single eye type, and with which is operatively' engaged an end portion of the dump rope l8. The opening l5 has its outer portion angular in contour to receive the head 19 of the pin H to prevent turning of the pin.

Secured to each side wall 2 and the adjacent side member 6 of the hood above but immediately adjacent to the cut-away portions 5 and I is a hitch plate 28 with a portion thereof extending beyond the adjacent edges of the hook H and body B. The plate 28 is rigidly held in place by the rivets 2! or otherwise as may be preferred. The forwardly extending portion'of each of the plates 20 is provided with transverse slots 22 to receive a load shackle, not shown.

The portions between the slots are apertured to form vertically spaced aligned eyes 22 to receive a suitable lock pin, not shown, by which the shackle is retained in working position.

Upon the top of the plate 20 are formed the upstanding perforated ears 29 to receive a holding pin, not shown, which, when applied, is disposed across the aligned eyes 22' to hold against upward displacement a lock pin inserted through the eyes.

Carried by the side walls 2 of the body B exteriorly thereof are the trunnion units T. Each of these units comprises a plate 3!, herein disclosed as substantially rectangular, and which is riveted, as at 32, Or otherwise rigidlysecured to a side wall 2 of the body B at a point rearwardly of the longitudinal center of the body B. The plate 3! at a desired point between its top and bottom margins is provided with an outstanding flange 33, the outer margin of which is continued by an upstanding relatively large wing 34.

' The upper portion of this wing 34 is provided with an opening 35 which is in alignment with an opening, not shown, in the plate 3|, and the opening 35 and the opening of the plate 3! receive a pin 31 which bridges the space between the wing 34 and plate 3! to engage through a rigid trunnion link such as is shown at 39, in

Figure 8.

The outer extremity of each of the trunnion. links 39 is adapted to have coupled thereto, as by the pin 45, in Figure 8, an end portion of a hoist chain 46 which is operatively engaged, as at 41-, in a conventional manner with a suitably oper-' ated block-and-tackle or other element whereby. the bucket may be raised or lowered. As diagrammatically illustrated in the accompanying drawings, this block-and-tackle or kindred element includes asheave 48 for the dump rope" l8; Associated with ;the entering or digging edge: ofthe bottom of the body B are the digging teeth A of desired number and spaced apart transversely of the body B. Each of these digging teeth comprises two sections 49 and 50, the section 49 constituting a base member and the section 50 a removable point member.

1 The base member or section 49 comprises an elongated arm 51 which underlies the forward portion of the bottom member 8 of the hood H and is welded or otherwise securely attached thereto. The forward portion of the arm 51 is provided with an upwardly and rearwardly disposed lug 52 which extends across in close contact with the beveled digging edge 9 and extends. inwardly thereof in close contact with the upper face of the forward portion of the bottom I of the body B and is welded or otherwise rigidly secured thereto.

The front portion of the lug 52 and the adjacent end portion of the arm 5| constitute a head 53, the outer face 0 of which is disposed on a predetermined downward and rearward incline. This face 0 is provided centrally with an elongated wedge-like arm 54 with the smaller end portion outwardly disposed. The rear portion of this arm 54 has disposed transversely therethrough a slot-like opening 55 which is adapted to register with the slot-like openings 56 in the side walls 51 of the tapered socket 58 in the rear end portion of the point 59.

A tapered key 60 is insertible through the registering openings 55 and 56 whereby the point 59 is effectively yet removably held in applied position. The smaller end portion of the key 60 is bifurcated, as at Bl. to allow said smaller end portion to be spread, after the key 60 has been applied, to hold the key against accidental displacement' It is to be noted that each of the arms 54 is disposed on a forward and downward incline and is of such length that when a point 59 is secured thereon the outer or digging end of said point will be below the bottom member 8 of the hood H.

The upper marginal portions of the side walls 2 and the rear wall 3 are provided therealong with the reinforcing strips 62 to prevent buckling or bending of such walls.

Underlying the bottom wall i of the body B and rigidly secured thereto, as by welding, are the runners 63 which are continued upwardly over the back or rear wall 3. These runners 63 also serve to materially strengthen or reinforce the bottom wall I and the rear wall 3. The reinforcing strips 62 extending along the upper margins of the s de walls 2 are welded to the rear edge of the hood H.

In the embodiment of the invention as illustrated in Figures 8 and 9, the general construction and assembly are substantially the same as her'einbefore disclosed with respect to the first embodiment of the invention except that the hood Y in itself comprises the front portion of the bucket body and the rear portion is of a skeleton structure to permit the draining off or liquid or fine materials as determined by the size of the openings in the walls of said rear portion.

The rear portion X comprises longitudinally disposed parallel strips 64 suitably coupled together. The forward end edges of the strips 64 butt the rear edge of the bottom 66 of the yoke Y and are" welded thereto. The rear portions of the strips 64 are continued upwardly, as at 61, to provide the back or rear wall of the body.

Each of the side walls of the rear portion X of the bucket body comprises the longitudinally or horizontally disposed spaced parallel strips 10 between which are interposed suitably spaced ver tical or cross members H having their end edges butting longitudinal edges of the strips 10 and welded thereto, with the lower members H having their bottom ends butting and welded to the' outer side strips 64 of the bottom wall.

facility with which it may be assembled and operated.

I claim:

A drag bucket comprising a relatively long body open at the top and at the front end, the body having a bottom portion which is transversely arcuate at the forward edge and which curves downwardly through a portion of its length at said forward edge, a reinforcing hood enclosing the bottom and sides of the forward end of the body and having a forwardly and downwardly curving bottom portion which extends beyond the forward edge of the bottom portion of the body, a plurality of tooth members each having a relatively long bottom arm and a relatively thick rounded lug of materially less length than and overlying and spaced from the arm, the space between the arm and the lug forming a slot for the reception of the forward edge portion of the bottom portion of the hood, the distance between the rear end of the lug and forward end of the slot substantially equalling the longitudinal extent of the forward portion of the hood beyond the bottom of the body whereby the rear end of said lug butts against the forward edge of the bottom portion of the body when the tooth is secured to the bottom portion of the hood, the top of the lug curving downwardly and rearwardly with respect to the top surface of the bottom portion of the body, and means for attaching drag and hoist lines to the bucket, the said forward edge of the bottom portion of the body being under-cut and. the curved top of the lug extending downwardly and rearwardly beneath and butting against the under-cut surface of the f0rward edge of the bottom portion of the body.
